HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 714,243, dated November25, 1902.

Application filed August 25, 1902.

To all whom it may concern:

Be it known-that 1, JAMES F.SARoENT,Jr.,a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of 'Michigan,have invented a new and useful Hose-Coupling, of which the following isa specification.

This invention relates to devices employed for immovably coupling theadjacent ends of to sections of hose, more particularly to that class ofdevices employed for the purpo'seof mendingbrokenor severed hose, andhas for its object'the construction of a-device which may be readily andquickly applied without the employment of extraneous implements otherthan an ordinary hammer or other similar tool or implement; and theinvention consists in a shank preferably tapered from the center towardthe ends and provided with a centrally-disposed annular rib and adaptedto be inserted into the adjacent ends of the hose-sections and twocollars engaging the shank on opposite sides of the rib and with lugsspaced apart and extending in opposite directions and preferablyinterlocking and adapted to be forcibly engaged with the oppositehose-sections.

Other novel features of the invention will appear in the annexeddescription and be 0 specified in the claims.

In the drawings illustrative of the invention, Figure 1 is a sideelevation of the device applied. Fig. 2 is a vertical longitudinalsection. Fig. 3is aperspective viewof the shank detached. Figs. land?)are perspective views of the gripping-collars detached. v

The improvement consists in a central shank or sleeve 10, preferablytapering in opposite directions from the central part toward the ends,and with a centrally-disposed annular rib l1 and preferably with annularend I ribs 12 13.

The sections of hose are represented, re-

spectively,at 14 15 and are adapted to engage 5 the oppositeends oftheshank 10 and be forced thereon, the tapered form of the shank expandingthe hose sections and causing them to grip the shank closer and obviatethe tendency to work loose. The shank thus 5o exerts a constantexpandingforce upon the Serial No. 120,977. (No model.)

this action and materially increase the grip caused by the resiliencyofthe hose.

Encircling the shank on opposite sides of the central rib 11 andbetweenthe rib and the adjacent ends of the hose-sections are collars 1617, the collar 16 provided with spaced lugs 18, extending over the rib11 and also over the end of the opposite hose-section 15, while thecollar 17 is likewise provided with spaced lugs 19,extending between thelugs 18 and over the end of the hose-section 14, as indicated in Fig. 1.

The extremities of thellugs 18 19 are provided, respectively, withinwardly-depending spurs 20 21, and when in position on the hose, asshown in Figs. 1 and 2, the lugs 18 19 will be forcibly bent inwardradially of the collars, and thus tightly compress the hose-sectionsagainst the shank and form a very strong holding meansthereto andlocking the parts all firmly together. Thiscompression of the hoseforces the hose material downward between the ribs 12 13 and the body ofthe shank,

as indicated in Fig; 2, thereby greatly increasing the grip and entirelyobviating any tendency of the hose-sections to work loose from theshank.

The spaces between the lugs 18 will be'sufficient to receive theopposite lugs 19 on the opposite collar, and the spaces between the lugs19 will be sufficient to receive the lugs 18 on the collar 16, asindicated in Fig. 1, the two-lugged collars thus being capable of beinginterlocked when in position, as indicated in Fig. 1, and adapted to befirmly locked to the hose and likewise firmly lock. the adjacenthose-sections to the coupling-sleeve. This makes a very simplehose-coupling and may be adapted to any size of hose and will firmlyunite them and enable them to resist any strains to which they would benaturally subjected while in use and will form a watertight joint. Bythis simple means a broken hose may be very quickly and readily mendedby severing the hose at the break and properly trimming the broken endsand forcing them upon the opposite ends of the shank, thereversely-disposed collars 16 17, with their reversely-disposed spursinterlocking, having been previously placed in position, as above noted,and the lugs 18 19, with their depending spurs 2O 21, forcibly engagedwith the hose.

The lugs 18 19 may be bent downward in engagement with the hose by anysuitable implement, preferably with a hammer, when the action will becomplete.

To detach the hose, it is only necessary to bend the lugs 18 19 outward,and if only one section is to be removed it is only necessary to detachthe lugs holding that particular section of hose.

Any required number of the lugs 18 may be employed, but generally fourwill be sufficient, as shown.

The collars 16 17 are precisely alike and will therefore beinterchangeable and may be manufactured very cheaply of sheet metal andof any weight or gage desired.

When completely united, the coupling presents no obstructions which maycatch upon grass or weeds or become charged with earth or other foreignmatter when dragged over the ground. This is a very important feature ofthe invention and adds very materially to its advantages, efficiency,and usefulness, as in many instances in dragging hose over the groundthe couplings catch upon obstructions and cause the rupture of thecoupling. With this device, however, such accidents will be obviated.

Another very important feature of this invention is found in the factthat the diameter of the coupling being substantially the same as thatof the hose permits the uninterrupted flow through the hose either ofsteam, water, or other liquid or air.

Having thus described the invention, what is claimed is 1. A hosecoupling comprising a shank having a centrally-disposed annular rib andadapted to engage the adjacent ends of sections of hose, collarsengaging said shank on opposite sides of said rib and having spaced lugsadapted to be reversely extended and forcibly engaged with the oppositehose-sections, substantially as described.

2. A hose-coupling comprising a shank havingreversely-tapered ends and acentrallydisposed annular rib and adapted to engage the adjacent ends ofsections of hose by said tapered ends, collars engaging said shank onopposite sides of said rib and having spaced lugs adapted to bereversely extended and forcibly engaged with the opposite hosesections,substantially as described.

3. A hose coupling comprising a shank having a centrally-disposedannular rib and with annular ribs upon its ends and adapted to engagethe adjacent ends of sections of hose, collars engaging said shank onopposite sides of said rib and having spaced lugs adapted to bereversely extended and forcibly compressed in engagement with the hosebetween said end ribs and said central rib, substantially as described.

at. A hose coupling comprising a shank having a centrally-disposedannular rib and adapted to engage the adjacent ends of sections of hose,collars engaging said shank on opposite sides of said rib and havingspaced lugs adapted to be reversely interlocked and oppositely extendedand forcibly engaged with the opposite hose-sections, substantially asdescribed.

5. A hosecoupling comprising a shank having a centrally-disposed annularrib and adapted to engage the adjacent ends of the sections of hose,collars engaging said shank on opposite sides of said rib and havingspaced lugs with their extremities bent inward and adapted to bereversely extended and forcibly engaged with the opposite hosesections,substantially as described.

6. A hose coupling comprising a shank having a centrally-disposedannular rib and with annular ribs upon its opposite ends and adapted toengage the adjacent ends of sections of hose, collars engaging saidshank on opposite sides of said rib and having spaced lugs with theirextremities bent inward and adapted to be reversely extended andforcibly engaged with the opposite hose-sections between said end ribsand said central rib, sub stantially as described.

7. In a hose-coupling, the combination of a shank having acentrally-disposed annular rib, hose-sections engaging the opposite endsof said shank, a collar engaging said shank between said rib and theadjacent end of one of said sections of hose and with lugs extendingtherefrom and adapted to be forcibly engaged with the other of saidsections of hose, a collar engaging said shank upon the opposite side ofsaid central rib and having lugs extending therefrom and adapted to beforcibly engaged with the opposite sect-ion of hose, substantially asdescribed.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
